The device has a pressure lever (46) comprising a gear segment (50) at a lever arm and a pressure piece (52) for application of force on a pressure surface (58). The gear segment is engaged with a gear rod (60) that is connected with a hand lever (12) and supported in a frame (18) such that a movement of the hand lever in an actuating direction effects a movement of the pressure piece in a direction towards the pressure surface. The pressure piece is arranged such that the piece contacts the pressure surface after reaching an intermediate position of the hand lever. |
